In an effort to crack down on counterfeiting, the Department of Homeland Security has begun targeting flea markets across the country in a series of high-profile raids that's led to the seizure of millions of dollars worth of merchandise.

The latest example is a recent raid in southwest Baltimore at Patapsco Flea Market, a 300,000 square foot space where 250 small vendors hawk goods and oddities — everything from live crabs to jewelry to clothing. Only open on Saturdays and Sundays, the marketplace was shut down this past Sunday after a two and a half year investigation by the Department of Homeland Security, which found that the market was selling counterfeit merchandise, The Baltimore Sun reported.

Federal agents discovered that nearly 70 percent of the brand name items at the store were allegedly fake and being sold as Nike, Polo, North Face, Louis Vuitton, Gucci and other brands. Confiscated items included 8,911 counterfeit DVDs worth $122,210; 10,699 counterfeit CDs worth $128,000; and 1,728 counterfeit items, including handbags, NFL merchandise and sneakers worth $648,000, according to the International Business Times.
